Correlations

First we calculate a correlation matrix for the tags.

Clustering

## Parallel analysis suggests that the number of factors =  8  and the number of components =  NA

## Parallel analysis suggests that the number of factors =  2  and the number of components =  NA

Using correlations, 3-6 clusters seems reasonable, so we can go with 5 as was previously useful. With the Jaccard similarity metric, more than 3 clusters seems like a stretch… for now we’ll leave this method behind.
